I’m trying to read an SD card for my blue pill. I’m using the online compiler. To be honest, the whole thing seems to be a mish-mash of new stuff, old stuff, and who knows what else.
Presumably (??) I want the FATFileSystem, although there seems so many file system libraries to choose from. So I do
but it says that there is no such file or directory. So presumably I need to import a library. There seem to be 9 implementations of the library (!), so I’m confused as to which one I should use. I think some of them are legacy stuff, too, so won’t work properly.
I don’t think I want mbed OS, which is presumably a fairly heavyweight RTOS system.
I’m confused. What do I need to do? How do I identify the “official” libraries?
